What I'm looking for

I seek a customer-focused role where I can apply my coordination, computer and leadership skills, support a collaborative team, and grow professionally—remote or on-site.

I am a detail-focused professional with experience in customer service, patient coordination, and instruction across retail, healthcare administration, and security settings.

I led teams, performed Medicare adjustments, edited PT accounts, completed audits and reports on time, and was the first on my team to work remotely; I am highly proficient with Microsoft Excel and other Office tools.

In my current role as a martial arts instructor, I teach children fundamentals, discipline, self-defense and life skills while also handling front-desk duties, parent communication and student assessment.

I am multilingual, a fast learner, comfortable working remotely or on-site, and motivated to contribute strong organizational, communication and technical skills to a collaborative team.
